DETAILED DESCRIPTION

FIG. 1 is a diagram of a laptop computer 100. Laptop computer 100 may include a base 102 and a lid 104. The base 102 and the lid 104 may be hingedly and/or rotatably connected to each other by a hinge 106. The hinge 106 may allow the lid 104 to rotate with respect to the base 102, and/or may enable the base 102 to rotate with respect to the lid 104. The base 102 may include computing components such as at least one processor 116 coupled to at least one memory device 118. The base 102 may also include at least one human interface device such as a trackpad 108 and/or keyboard 110. The lid 104 may include a display 112. The display 112 may present images to a user. The display 112 may be electrically coupled to the processor 116 included in the base 102 via electronic circuitry included in the hinge 106.

As mentioned above, the hinge 106 may allow the base 102 and lid 104 to rotate with respect to each other, enabling a user to close the laptop computer 100 for storage by rotating the lid 104 toward the base 102 so that the display 112 and keyboard 110 are facing each other. The hinge 106 may also enable the user to open the laptop computer 100 by pulling the lid 104 away from the base 102 so that the display 112 is visible to the user and the user has room to type into the keyboard and touch the trackpad 108. The hinge 106 may be cylindrical. The cylindrical shape of the hinge 106 may make it difficult for the hinge 106 to accommodate non-cylindrical components.

The hinge 106 may include and/or define a recess 114, which may be cylindrical itself with an axis parallel to, or aligned with an axis of the cylindrical hinge 106. The recess 114 may include or be adjacent to electrical contacts. The electrical contacts may carry electrical signals, such as audio signals to and/or from an electronic device, such as a headphone set, speakers, and/or microphone, outside the laptop computer 100, from and/or to components inside the base 102 such as the processor 116.

The recess 114 may be cylindrical. The substantially cylindrical shape of the recess may correspond to the cylindrical shape of the hinge 106, minimizing a volume of the hinge 106 interposed between the recess 114 and an outer surface of the hinge 106. The recess 114 may have a diameter of, for example, no more than 6.4 millimeters, or less than 6.4 millimeters. The recess 114 may receive a jack (not shown in FIG. 1), such as an audio jack, which may couple to the electrical contacts included in or adjacent to the recess 114, and communicate with the components in the base 102. It may be desirable to minimize a size of the jack so that the jack may fit into the recess 114.

FIG. 2A is a perspective view of a jack 200 according to an example embodiment. The jack 200 may include an audio jack that carries electronic signals representing audio input and/or output. The jack 200 may be inserted into the recess 114 (shown in FIG. 1). The jack 200 may, when inserted into the recess 114, couple with the electrical contacts included in or adjacent to the recess 114, carrying electrical signals between the electronic components included in the base 102 (shown in FIG. 1) and the electronic device outside the laptop compute 100.

The jack 200 may include a housing 204. The housing 204 may be made of an insulative material, such as plastic. The housing 204 may be generally cylindrical, with apertures that receive components and a cylindrical cavity (not shown in FIG. 2A) that receives a plug. The housing 204, being generally cylindrical, may have a cross section that is bounded by an imaginary cylinder having a diameter, D, such that any dimension of the housing 204 transverse to the axis of the housing is less than or equal to D, thus allowing the housing 204 to fit into the recess 114. The generally cylindrical shape of the housing 204 may cause a majority of an outer surface 205 of the housing 204 to be adjacent to, and/or contiguous with, the imaginary cylinder. The adjacency of the majority of the outer surface 205 of the housing 204 to the imaginary cylinder may cause the majority of the outer surface 205 of the housing 204 to be within a small distance of the imaginary cylinder. The small distance may be, for example one-tenth of a millimeter (0.1 mm), or one percent (1%), two percent (2%), three percent (3%), four percent (4%), or five percent (5%), of the diameter of the housing 204 and/or of the diameter of the imaginary cylinder.

The imaginary cylinder that the housing 204 is bounded by may have a diameter equal to or greater than the diameter of the recess 114. The imaginary cylinder may, for example, have a diameter of no more than 6.4 millimeters, and/or less than 6.4 millimeters. The 6.4 millimeter diameter may be a maximum size of the recess 114 that allows the hinge 106 (shown in FIG. 1) to have sufficient strength not to break without increasing a size of the hinge 106 to an undesirable size. The closeness, adjacency, and or contiguity of the outer surface 205 of the housing 204 to the imaginary cylinder, which may correspond to and/or be equivalent to the recess 114, may enable the housing 204 to be friction-fitted into the recess 114.

The jack 200 may receive a plug 202. The plug 202 may include, for example, an audio pin or other electrical component that sends and/or receives electrical signals to and from the laptop computer 100 (shown in FIG. 1). The plug 202 may extend into a cavity (not shown in FIG. 2A) defined by the housing 204.

The jack 200 may include contact clips 206A, 206B, 206C. The contact clips 206A, 206B, 206C may include at least one contact clip and/or may include a first contact clip 206A, a second contact clip 206B, and a third contact clip 206C. The contacts clips 206A, 206B, 206C may be made of a conductive material, such as metal. The contact clips 206A, 206B, 206C may extend through contact apertures (referenced in subsequent figures) defined by the housing 204 and into the cavity defined by the housing 204.

The contact clips 206A, 206B, 206C may be friction-fitted into the contact apertures. The contact clips 206A, 206B, 206C may be friction-fitted into the contact apertures by flanges of the contact clips 206A, 206B, 206B being friction-fitted into slots defined by the contact apertures, and/or by an angle of extension of an arm of the contact clip 206A, 206B, 206B from a body of the contact clip 206A, 206B, 206C increasing when the contact clip 206A, 206B, 206C is inserted into the contact aperture. The contact clips 206A, 206B, 206C may contact portions of the plug 202 which send and receive electrical signals between the laptop computer 100 and a device coupled to the plug 202.

The jack 200 may include a printed circuit board (PCB) 208. The PCB 208 may include electrical contacts (shown in FIG. 4) coupled to the contact clips 206A, 206B, 206C, as well as to detection contacts (not shown in FIG. 2A). The PCB 208 may be flexible and/or include a flexible PCB, enabling the PCB 208 to bend and/or depress when the jack 200 is inserted into the recess 114. When the jack 200 is outside the recess 114, the PCB 208 may extend beyond the imaginary cylinder that bounds the housing 204. The bending and/or depressing of the PCB 208 may cause the PCB 208 to stay within the imaginary cylinder and/or recess 114 when the jack 200 is inside the recess 114.

FIG. 2B is a diagram showing the jack 200 without the PCB 208. As shown in FIG. 2B, the housing 204 of the jack 200 may define a cavity 210. The cavity 210 may be cylindrical, and may include an opening at a first end (referenced in FIG. 2C) of the housing 204, and may be closed at a second end (shown in FIG. 2C) of the housing 204. The cavity 210 may receive the plug 202 (not shown in FIG. 2B).

The jack may include a securement clip 212. The securement clip 212 may be made of either an insulative material or a conductive material. The securement clip 212 may be made of a rigid yet flexible material, such as metal. The securement clip 212 may extend through the housing 204, and through a securement aperture defined by the housing 204, into the cavity 210.

The securement clip 212 may be configured to bend toward the outer surface 205 of the housing 204, and/or reduce a radius of curvature of a rounded portion (shown in FIGS. 5A, 5B, 5C, and 5D), in response to the cavity 210 receiving the plug 202. The securement clip 212 may press away from the outer surface 205 and into the cavity 210 against the plug 202, thereby securing the plug 202 in the cavity 210 by a friction fit.

The jack 200 may also include a flexible detection clip 214 extending from outside the housing 204 through a flexible detection aperture into the cavity 210. The flexible detection clip 214 may be made of a conductive material, such as metal. The jack 200 may also include a rigid detection clip 216 extending through a rigid detection aperture from outside the housing 204 into the cavity 210. The rigid detection clip may be made of a conductive material, such as metal.

The flexible detection clip 214 may, in response to the plug 202 being inserted into the cavity 210, bend away from the first end of the jack 200, reducing a radius of curvature of a rounded portion (shown in FIGS. 6A, 6B, 6C, 6D, and 6E) of the flexible detection clip 214, and make contact with the rigid detection clip 216. The contacting of the rigid detection clip 216 by the flexible detection clip 214 may electrically couple the flexible detection clip 214 to the rigid detection clip 216.

The PCB 208 (not shown in FIG. 2B) may include a plug inserted circuit. The plug inserted circuit may detect when the flexible detection clip 214 and the rigid detection clip 216 are electrically coupled together. The PCB 208 may, in response to determining that the flexible detection clip 214 and rigid detection clip 216 are electrically coupled to each other, send a plug inserted signal to a device, such as a device or component included in the laptop computer 100 (such as the processor 116), indicating that the plug 202 has been inserted in the cavity 210 of the jack 200.

The housing 204 may also include an insulator 218. The insulator 218 may be a piece of material included in the housing 204, which is located between, and/or disposed between, the flexible detection clip 214 and the rigid detection clip 216. Insulator 218 may ensure that the flexible detection clip 214 and the rigid detection clip 216 are not electrical coupled until after the plug 202 has been inserted into the cavity to 210.

FIG. 2C is another diagram showing the jack 200. The first contact clip 206A may be closer to the first end 220 than the second contact clip 206B, third contact clip 206C, securement clip 212, flexible detection clip 214, and rigid detection clip 216. The second contact clip 206B may be closer to the first end 220 than the third contact clip 206C, securement clip 212, flexible detection clip 214, and rigid detection clip 216. The third contact clip 206C may be closer to the first end 220 than the securement clip 212, flexible detection clip 214, and rigid detection clip 216. The securement clip 212 may be closer to the first end 220 than the flexible detection clip 214 and rigid detection clip 216. The flexible detection clip 214 may be closer to the first end 220 than the rigid detection clip 216. This is merely an example. The components of the jack 200 may be arranged in any order.

As shown in FIG. 2C, the flexible detection clip 214 is located near the rigid detection clip 216. In response to the plug 202 being inserted into the first end 220, the flexible detection clip 214 will bend toward the second end 222, reducing a radius of curvature of a rounded portion (referenced in FIGS. 6A, 6B, 6C, 6D, and 6E) of the flexible detection clip 214 until the flexible detection clip 214 contacts the rigid detection clip 216. When the plug 202 is inserted into the first end 220, the rounded portion of the securement clip 212 will bend toward the portion of the housing 204 closer to the top of the page and press back toward the plug 202, securing the plug 202 in the jack 200 by a friction fit.

FIG. 2D is a diagram showing the housing 204. As shown in FIG. 2D, the housing 204 includes a planar surface 310 portion. The planar surface 310 may receive the flexible PCB 208, and/or the flexible PCB 208 may rest on the planar surface 310.

The contact apertures (not referenced in FIG. 2D) that receive the contact clips 206A, 206B, 206C may include and/or define slots 241, 242, 244, 246, 248, 250. Protrusions 230, 232, 234, 236, 238, 240 of the housing 204 may define the slots, 241, 242, 244, 246, 248, 250. The slots 241, 242, 244, 246, 248, 250 may receive flanges (shown in FIGS. 8B and 8C) of the contact clips 206A, 206B, 206C. The receipt of the flanges by the slots 241, 242, 244, 246, 248, 250, and/or insertion of the flanges into the slots 241, 242, 244, 246, 248, 250, may secure the contact clips 206A, 206B, 206C into the housing 204 by friction-fitting the flanges into the slots 241, 242, 244, 246, 248, 250.

FIG. 2E is another diagram showing the housing 204. FIG. 2E shows the protrusions 230, 232, 234, 236, 238, 240 which define the slots 241, 242, 244, 246, 248, 250 (the slots are not referenced in FIG. 2E).

FIG. 2F is a diagram of the jack 200 viewed from the first end 220 (not referenced in FIG. 2F). As shown in FIG. 2F, the securement clip 212 extends through an aperture (not referenced in FIG. 2F) in an inner surface 211 of the housing 204 and into the cavity 210. The flexible detection clip 214 also extends into the cavity 210. The contact apertures (not shown in FIG. 2F) make room for protrusions on the contact clips 206A, 206B, 206C. The contact clips 206A, 206B, 206C extend into the cavity 210 so that protrusions of the contact clips 206A, 206B, 206C may contact portions of the plug 202 (not shown in FIG. 2F).

FIG. 2G is another diagram of the jack 200. The imaginary cylinder 226 may have a diameter 228 equal to or slightly greater than the diameter of the housing 204 of the jack 200. The diameter of the imaginary cylinder 226 may, for example, be no more than one millimeter greater, one percent greater than the diameter of the housing tool, two percent greater, three percent greater, four percent greater, and/or five percent greater than the diameter of the housing 204, according to various example embodiments. Components of the jack 200, including some, all, or any combination of the PCB 208, contact clips 206A, 206B, 206C, securement clip 212, flexible detection clip 214, and/or rigid detection clip 216, may extend beyond the imaginary cylinder 226 (while the housing 204 is bounded by the imaginary cylinder 226), or all of the components of the jack 200 may be bounded by the imaginary cylinder 226.

FIG. 3A shows an exploded view of the jack 200 and plug 202. The plug 202 may include a backstop 302 connected to a barrel 304. The backstop 302 may be cylindrical, and/or the barrel 304 may be cylindrical. The backstop 302 may have a greater diameter than the barrel 304. The greater diameter of the backstop 302 may prevent the plug 202 from being inserted into the cavity 210 beyond a predetermined distance. The backstop 302 may be coupled to another device, such as headphones, a speaker, and/or a microphone.

The barrel of the plug 202 may include one or more, such as three, contacts 306A, 306B, 306C. The contacts 306A, 306B, 306C may be electrically isolated from each other, and may carry separate signals. The contacts 306A, 306B, 306C may contact the contact clips 206A, 206B, 206C, respectively. The barrel 304 may also include an end 308. The end 308 may contact the flexible detection clip 214, pressing the flexible detection clip 214 and causing the flexible detection clip 214 to contact the rigid detection clip 216.

The housing 204 may define contact apertures 326A, 326B, 326B which receive the contact clips 206A, 206B, 206C and extend from the outer surface 205 of the housing 204 to the cavity 210. The housing 204 may define a securement aperture 312 that receives the securement clip 212 and extends from the outer surface 205 of the housing 204 into the cavity 210. The housing 204 may define a flexible detection aperture 314 which receives the flexible detection clip 214 and extends from the outer surface 205 of the housing 204 to the cavity 210. The housing 204 may define a rigid detection aperture that receives the rigid detection clip 216 and extends from the outer surface 205 of the housing 204 to the cavity 210.

FIG. 3B is a diagram showing the housing 204. As shown in FIG. 3B, the contact apertures 326A, 326B, 326C may include circular, elliptical, and/or rounded apertures 336A, 336B, 336C. The circular, elliptical, and/or rounded apertures 336A, 336B, 336C may allow the protrusions (shown but not referenced) of the contact clips 206A, 206B, 206C to extend through the housing 204 into the cavity 210.

As discussed above, the protrusions 230, 232, 234, 236, 238, 240 (shown but not referenced in FIG. 3B) of the housing 204 may define the slots 241, 242, 244, 246, 248, 250 which receive the flanges of the contact clips, 206A, 206B, 206C, thereby friction fitting the contact clips 206A, 206B, 206C into the housing 204.

FIG. 3C is another diagram of the housing 204. The contact apertures 326A, 326B, 326C may receive the contact clips 206A, 206B, 206C (not shown in FIG. 3C). Securement aperture 312 may receive the securement clip 212 (not shown in FIG. 3C). Flexible detection aperture 314 may receive the flexible detection clip 214 (not shown in FIG. 3C). Rigid detection aperture 316 may receive the rigid detection clip 216 (not shown in FIG. 3C). Insulator 218, which may be a portion of the housing 204, may be disposed between the flexible detection aperture 314 and the rigid detection aperture 316.

FIG. 4 is a diagram of the PCB 208. The PCB 208 may include contacts 406A, 406B, 406C, which contact and/or are electrically coupled with the contact clips 206A, 206B, 206C (not shown in FIG. 4) when the PCB 208 is placed on the planar surface 310 (not shown in FIG. 4) of the housing 204. The contacts 406A, 406B, 406C may route signals from the contacts 306A, 306B, 306C (not shown in FIG. 4) of the plug 202 (not shown in FIG. 4), through the contact clips 206A, 206B, 206C (not shown in FIG. 4), to electrical components such as the processor 116 included in the base 102 of the laptop computer 100.

The PCB 208 may also include contact 414 that contacts the flexible detection clip 214 (not shown in FIG. 4), and contact 416 that contacts the rigid detection clip 216 (not shown in FIG. 4). The contacts 414, 416 may be included in a plug inserted circuit that detects whether the flexible detection clip 214 and rigid detection clip 216 are electrically coupled to each other and provide an indication of whether plug 202 has been inserted into the cavity 210.

FIGS. 5A, 5B, 5C, and 5D are diagrams of the securement clip 212. As shown in the figures, the securement clip 212 may include a planar body 502. An arm 504 may extend from the body 502. The arm 504 may be planar and/or have a planar portion. The arm 504 may extend from the body 502 at a right angle, and/or may have a portion which extends along a plane that is a right angle from the body 502. The arm 504 may have a portion which extends along a plane, which is approximately perpendicular to a plane of the body 502, such as between 85° and 95° from, the plane of the body 502. The securement clip 212 may include a rounded portion 506. Rounded portion 506 may extend from the body 502. The rounded portion 506 may be round, and may be configured to bend in response to the cavity 210 (not shown in FIG. 5A, 5B, 5C, or 5D) receiving the plug 202 (not shown in FIG. 5A, 5B, 5C, or 5D). A radius of curvature of the rounded portion 506 may be reduced and/or become smaller when the cavity 210 receives the plug 202 and the plug 202 presses against the rounded portion 506. The rounded portion 506 may press back against the barrel 304 of the plug 202, providing a friction fit to the plug 202.

FIGS. 6A, 6B, 6C, 6D, and 6E are diagrams of the flexible detection clip 214. The flexible detection clip 214 may include a body 602. The body 602 may be planar. The flexible detection clip 214 may also include an arm 604. The arm 604 may contact the contact 414 (not shown in FIG. 6A, 6B, 6C, 6D, or 6E) of the PCB 208 (not shown in FIG. 6A, 6B, 6C, 6D, or 6E). The arm 604 may be planar, and/or may extend from the body 602. The arm 604 may extend from the body 602 at a right angle, or nearly a right angle. The arm 604 may, for example, extend along a plane which is between 85° and 95° from a plane along which the body 602 extends.
